The Real-time Style Performer (RSP) gives you the ability to play musical styles created for Yamaha PSR musical instruments through a PC sound card. The program is solely dedicated to real-time “live” performance with a MIDI keyboard connected to PC, like it is done by the auto accompaniment PSR keyboards. It is not a sequencer of any kind and it does not create midi files. By this the RSC introduces new abilities and does not cross performance of the other software applications and utilities available on the market, which deal with Yamaha PSR styles and MIDI. With such MIDI commutation utilities like Hubi’s Loopback Driver one may always connect the RSP to a sequencer for recording and subsequent editing, if there is need for that. »
